标准摘要
[中文适用范围]： 本国际标准规定了一种喷雾测试方法，用于测定任何织物（可能已或未经过防水或拒水整理）表面被水润湿的抵抗力。 它不适用于预测织物的抗雨水渗透性，因为它不测量水渗透织物的情况。 [外文原描述]： ISO 4920:2012 specifies a spray test method for determining the resistance of any fabric, which might or might not have been given a water‑resistant or water‑repellent finish, to surface wetting by water. It is not intended for use in predicting the rain-penetration resistance of fabrics, since it does not measure penetration of water through the fabric.
英文名称Textile fabrics — Determination of resistance to surface wetting (spray test)
